Faast portfolio wants to be a faster and easier way than Shapeshift to exchange and even organize all of your crypto investments.
Faast portfolio makes this whole process very simple by allowing you to connect your MetaMask, Trezor, or Ledger wallet to the Faast portfolio and quickly swap between coins securely without needing to visit any exchanges. The Faast portfolio also includes the Mist Browser and Parity plug-ins as well. You could also use a keystore file, but this probably isn't recommended.
In order to begin using Faast, you simply connect your MetaMask, Ledger, etc. wallet and begin trading your current holdings for the coins you want right away without needing to exchange your holdings for BTC/ETH etc. first. There is also no membership or sign-up required.
Shapeshift already allows you to exchange one coin for another, but with Faast you can choose from over 100 supported tokens with more to come. With Faast you are able to choose the coin you want from a list, exchange it, and then within a few minutes you'll have a well-diversified portfolio/pie chart that will show all of your current holdings. Also, Faast mentions that all of your tokens stay safe as the swap happens over the Faast network before being sent to your Trezor wallet, etc.
In fact, the only downside to Faast seems to be that it is not completely free, they charge a small fee to conduct trades, but this is nothing new. On their website Faast compares a $100 swap between Aragon (ANT) and Aeternity (AE) and shows that you're left with about $95 after the exchange. Faast portfolio is still in Beta, but I think I'll start using it soon.
